probably alright as its held in the spigot bush in the flywheel, does it rotate smooth enough
It seems to, certainly no noises
Thanks for your help so far, I'm sure I'll have more questions when I get the top off!

You can select each gear in turn.[ you have taken care with detent balls ] Then turn the input shaft by hand while looking at the gears checking each in turn looking for any damaged teeth. Hard to see with selectors in place but what I can see look good. Everything should turn smoothly

With the transfer box you can remove the bottom plate for a good look / clean out. Re fit with new gasket.

What tottot said, not forgetting the reverse pinion right down in the bottom, plus: make sure the detent springs on the 3rd/4th synchro hub are all present and correct. They are the little leaf spring wotsits that sometimes come out and get mangled, there should be three of them. Now would be a good time to replace all the oil seals on the gearbox as well.
Edit: just remembered: also make sure the set-bolt in the end of the layshaft hasn't come loose; they do from time-to-time and can cause a buggered layshaft. It's under the little cover inside the bell housing. Fit a new set-bolt if it has come loose and Loctite it.

It is not hard to remove the selectors for a better look,but they do come out and go back in a certain order. [ if you do remove a video of how you do it would help replacement.]
Thank you for all the replies so far. Yes it had an overdrive on before i got it. Im going to swop the missing bits off my old box.
Ok I've just had a poke around in there and moved all through all the gears and all looks good to me,the only noise is when I push down and turn the mainshaft from the bell housing end.
There's are lots of bits of muck and gasket sealent on the gears which I'm certain have come from when I've lifted the cover off, I'm thinking is it ok to just wash it down to the bottom of the box with some de greaser and flush out.
I'm going to remove the transfer box and re use my own, as I know it's been fine and remove the bell housing as I presume I will need to keep my 2a bell housing to go with the clutch slave.

+ 1 on the above. The 2a clutch release is a much better job than the 3 one.
That's tommorows job! I'll be back with more pics
I have read that before on here, thanks for confirming it to me
...so got the clutch thingy off
didnt realised bell housing wouldnt come off without pulling the main shaft with it, and I carnt get layshaft nut off because I've nothing to hold onto on other end of mainshaft... hope that makes sense.will have to use a wooden post and my son holding it tomorrow to get the nut off.
How does the bell housing sepesepa from the shaft please?

mainshaft doesnt come out, if you have top off remove the interlock between the shafts and select 2 gears,16mm socket fits the bolt, tap the 3 bell housing bolts out too it helps with refitting
Thank you james that's tomorrows job sorted. Was the main shaft pulling out because I haven't undone the lay shaft bolt?

nut must be off the back of the mainshaft but they are usually quite a tight fit through the bearing, your trying to pull layshaft which is pulling on m/s
Here's some pictures for your amusement!
